PI-BD (Processor Interface Circuit Pack)
k. Error type 3999
control channel messages to the switch within a short period of time. If
error type 1538 is also present, then the circuit pack was taken
out-of-service due to hyperactivity. If error type 1538 is not present, then
the circuit pack has not been taken out-of-service, but it has generated
50% of the messages necessary to be considered hyperactive. This may
be completely normal during heavy traffic periods. However, if this error
type is logged when the circuit pack is being lightly used, it may indicate a
problem with the circuit pack or the equipment attached to it.
System Technician Demanded Tests: Descriptions
and Error Codes
Always investigate tests in the order presented in the table below when inspecting
errors in the system. By clearing error codes associated with the Standby
Processor Interface Circuit Pack Test, for example, you may also clear errors
generated from other tests in the testing sequence.
Standby Processor Interface Circuit Pack Test
(#423)
Standby Processor Interface Port Test (#404) (a)
Control Channel Loop Test (#52)
NPE Audit Test (#50)
1 D = Destructive; ND = Nondestructive
Note:
a. This test is repeated up to four times since there are four ports on the
circuit pack. Cross-reference PI-PT (Processor Interface Port)
Maintenance documentation for information about these tests.
Control Channel Loop Around Test (#52)
Refer to the repair procedure described in the XXX-BD (Common Port Circuit
Pack) Maintenance documentation as Control Channel Loop Around Test (#52).
NPE Audit Test (#50)
Refer to the repair procedure described in the XXX-BD (Common Port Circuit
Pack) Maintenance documentation as NPE Audit Test (#50).
